11. Description
Axion 2thermal imaging monoculars are designed for use both at night-
time and during the day and provide exceptional image quality even in
adverse weather conditions (fog, smog, rain) and beyond obstacles like
branches, tall grass, dense foliage, etc. known to hinder target detection.
Unlike night-vision devices based on electron-optical converters, thermal
imaging devices do not need an external light source and are resistant to
bright light.
Axion 2thermal imagers are designed for various applications including
hunting, observation, security, terrain orientation, search and rescue
operations, etc.

* Available separately
** Standby mode is when the batteries are in the charger but the Power
Adapter is not connected. In this mode, the indicators are only on for 10
seconds.
Attention! When using a Power Adapter that does not support USB Power
Delivery fast charging technology, the flicker frequency of the LED
indicators decreases by a factor of 3 and the charge time increases.
Attention! The charger heats up during fast charging. Excess heat is
removed through the radiator and does not affect the device operation.

23. Battery Installation
1. Put the Lock-cover (12) on the rechargeable APS 5 battery (11).
2. Insert the APS 5 battery (11) along the guide into the battery
compartment (13).
3. Lock the battery (11) by turning the Lock-cover (12)clockwise until it
stops.
4. Turn the Lock-cover (12) counter-clockwise to remove the battery (11).

24. External Power Supply
Show device diagram
External power can be supplied from an external source, such as a Power
Bank (5 V, 9 V).
1. Connect the external power source to the USB Type-C connector (9) on
the device.
2. The device will switch to draw power from the external source while the
АPS5 battery is gradually recharged.
3. A battery icon will appear on the display showing the percentage-
charged level.
4. An icon will be displayed when the device is powered by an

25. external power source and the АPS5 battery is not connected.
5. The device automatically switches to the APS 5 battery when the
external power supply is disconnected.
Attention! Charging APS 5 batteries from an external source at
temperatures below 0°C (<32°F) can reduce battery life. When using
external power, connect the power bank to the device only after it has been
turned on and working (warming) for at least several minutes.

26. Precautions
Always use the APS 5 charger (purchased separately) to charge APS 5
batteries. Using an unsuitable charger can cause irreparable damage to
the battery and fire.
Do not charge the battery immediately after exposure to a cold
environment. Let the battery warm for at least 30 minutes before
charging.
Do not leave the battery unattended while charging.
Do not use the charger if it has been modified or damaged.
Do not leave the battery in a plugged-in charger after charging is
complete.
Do not expose the battery to high temperatures or open flames.
Do not use the battery as a power source for devices that do not support
APS 5 batteries.
Do not disassemble or deform the battery or charger.
Do not drop or strike the battery or charger.
Protect the battery and charger from water and moisture.
Keep the battery out of the reach of children.

27. Recommendations for Use
The batteries should be partially charged (50 to 80 %) for long-term
storage.
Charge at an ambient temperature of 0°C to +35°C (32°F to 95°F) or
the lifespan of the battery will decrease significantly.
Using the battery at sub 0°C (<32°F) ambient temperature decreases
battery capacity. This is normal and not a defect.
Using the battery at temperatures outside the range of -25°C to +40°C (-
13°F to 104°F) may reduce battery life.
The battery is short-circuit protected. Any situation that may cause
short-circuiting should be avoided.

54. Technical Inspection
It is recommended to carry out a technical inspection before each use of the
device. Check the following:
The device appearance (there should be no cracks on the body).
The condition of the lens and eyepiece (there should be no cracks,
grease spots, dirt or other deposits).
The state of the rechargeable battery (should be charged) and the
electric contacts (should be no signs of salts, oxidation or debris).
The controls should be in working order.

55. Technical Maintenance
and Storage
Maintenance should be carried out no less frequently than twice a year, and
should consist of the following measures:
Wipe external plastic and metal surfaces with a cotton cloth to remove
dust and dirt. To avoid damage to the paint coating, do not use
chemically active substances, solvents, etc.
Clean the electric contacts of the Battery Pack and the device's battery
slot using a non-greasy organic solvent.
Check the objective and eyepiece lenses and if required, remove dust
and dirt (preferably using a non-contact method). Cleaning of the
exterior surfaces of the optics should only be done with products
specifically designed for this purpose.
Store the device in a carrying case. Remove the Battery Pack for long-
term storage.

56. Troubleshooting
The device does not turn on
Possible cause
Battery Pack is discharged.
Solution
Charge the Battery Pack.
The device does not operate from an
external power source
Possible cause
The USB cable is damaged.
Solution
Replace the USB cable.
Possible cause
The external power supply is discharged.
Solution
Charge the external power supply (if necessary).
The image is blurry, with vertical stripes or
an uneven background

57. Possible cause
Calibration is required.
Solution
Perform the calibration according to Calibration Modesection.
Black screen after calibration
Solution
If the image does not clear after calibration, you need to recalibrate.
Poor quality image. There is noise or ghost
images of previous scenes or objects
Possible cause
Manual calibration has been performed with the lens cover open.
Solution
Check the Calibration Mode, close the lens cover and calibrate the
device.
The image is too dark
Possible cause
Brightness or contrast level is too low.
Solution
Adjust the brightness or contrast level in the Quick Menu.
Color bars appear on the display or the
image disappears

58. Possible cause
The device was exposed to static electricity during operation.
Solution
After exposure to static electricity, the device may either reboot
automatically or require turning off and on again.
The image of the object being observed is
missing
Possible cause
You are looking through glass.
Solution
Remove the glass or change the viewing position to avoid it.
Poor image quality / Detection range reduced
Possible cause
These problems may occur during observation in adverse weather
conditions (snow, rain, fog, etc.).
Smartphone or tablet PC cannot be
connected to the device
Possible cause
Device password has been changed.
Solution
Delete the network and connect again using the password saved in the
device.

59.
Possible cause
The device is in an area with too many Wi-Fi networks that may be
causing signal interference.
Solution
To ensure a stable Wi-Fi connection, relocate the device to an area with
fewer or no Wi-Fi networks.
Possible cause
The device has a 5 GHz network enabled, but the smartphone only
supports 2.4 GHz.
Solution
Switch the device's Wi-Fi bandwidth to 2.4 GHz.

Wi-Fi signal is missing or interrupted
Possible cause
Smartphone or tablet is out of range of a strong Wi-Fi signal. There are
obstacles between the device and the smartphone or tablet (e.g.,
concrete walls).
Solution
Relocate smartphone or tablet into the Wi-Fi signal line of sight.

60. 2 by following the link.
The image quality during the device
operation at below zero temperatures is
worse than at positive temperatures
Possible cause
Because of variations in thermal conductivity, objects (surrounding
environment, background) under observation become warm more
quickly at above-zero temperatures, which allows higher temperature
contrast, so the quality of the image produced by a thermal imager will
be better.
At low operating temperatures, objects under observation (background)
normally cool down to roughly identical temperatures, which leads to
reduced temperature contrast and to image quality (precision)
degradation. This is normal for thermal imaging devices.
